The Cold Stone PB&C milkshake, made with peanut butter, chocolate ice-cream and milk, contains 68 grams of saturated fat and 153 grams of sugar, according to nutritional details on the company's website.

"In terms of saturated fat, drinking this Cold Stone catastrophe is like slurping up 68 strips of bacon," the magazine said.

The second worst drink in America was listed as the Peanut Power Plus Grape from Smoothie King with a large cup packing 1,498 calories and the same amount of sugar as 20 Reese's Peanut Butter Cups chocolate and peanut butter snacks.

McDonald's large Triple Thick Chocolate Shake came in third with 1,160 calories or the equivalent of 13 of the fast food chain's hot apple pies.

A spokesman from the Cold Stone Creamery pointed out that the company does also offer low-calorie, reduced-fat options for customers looking for "a lighter indulgence" such as its range of sinless smoothies with only 110 calories.
